Overview
7
Two ways to customize configurations of your SIP-T27P IP phone:
The user interface on the IP phone.
The user interface in a web browser on your PC.
The hardware components keypad and LCD screen constitute the phone user interface,
which allows the user to execute all call operation tasks and basic configuration
changes directly on the phone. In addition, you can use the web user interface to
access all configuration settings. In many cases, it is possible to use either the phone
user interface and/or the web user interface interchangeably. However, in some cases,
it is only possible to use one or the other interface to operate the phone and change
settings.
You can customize your phone by pressing the Menu soft key to access the phone user
interface. The Advanced Settings option is only accessible to the administrator, and the
default administrator password is “admin”(case-sensitive). For more information on
customizing your phone with the available options from the phone user interface, refer
to Customizing Your Phone on page 25.
In addition to the phone user interface, you can also customize your phone via web user
interface. In order to access the web user interface, you need to know the IP address of
your new phone. To obtain the IP address, press the OK key on the phone when the
phone is idle. Enter the IP address (e.g., http://192.168.0.10 or 192.168.0.10) in the
address bar of a web browser on your PC. The default administrator user name and
password are both “admin”(case-sensitive).
The options you can use to customize the IP phone via phone user interface and/or via
web user interface are listed in the following table:
